How good is the steel?
Lots of terms are used in product descriptions. "Heavy duty" and "heavy gauge" does not tell you a thing. Ask before you buy!
"Schedule" gives you the resistance to impact based on thickness of wall and outside diameter of the steel. The steel must get thicker as the diameter gets larger to maintain the same integrity against pucks! A 1 3/4" (1.75") pipe @ .065" (1.58mm) thickness is very weak (even thinner is very common in stores and small manufacturers) compared to our 1 3/8"(1.375") inch pipe of the same thickness. Our 2" pipes are .109" (2.77mm) thick and our 2 3/8 "(2.375") pipes are .125" (31.75mm) thick, as in an regulation NHL goal crossbars. Please compare.
"Gauge" tell you the actual wall thickness. The numbers on this scale go down as the material gets thicker.
fraction decimal mm gauge
1/19" .055" 1.4mm 17.2
1/16" .065" 1.58mm 16
1/10" .109" 2.77mm 12.4
1/8" .125" 3.2mm 10.4
Outside Diameter is the size you see. Our post and crossbar sizes are in bold below. Other OD's we've seen are also listed.
1 3/8" / 1.375" .065" (1.58mm) thick wall
1 1/2" / 1.5" Must be at least .080thick, (2.03mm) to have same integrity as ours
1 5/8" / 1.625" Must be at least .086thick, (2.18mm) to have same integrity as ours
1 3/4" / 1.75" Must be at least .092 thick, (2.34mm) to have same integrity as ours
2 " / 2.00" .109"(2.77mm) thick wall
2 1/4" / 2.125" Must be at least .1125 thick, (2.87mm) to have same integrity as ours.
2 3/8" / 2.375" .125"(3.20mm) thick wall
